I need Indian scripts display in applications created using UPP.

To display Indian fonts HarfBuzz usage is required.

All Indian scripts are very complex. All these complexcities are handled by HarfBuzz.

We have conjuncts (joined glyph ) some times with up to 5 chars and multi tier. Some char sequences are interchanged for display.

Steps required for Display India String.

Load and init font with HarfBuzz functions
Shape the string with HarfBuzz function. This gives correct glyph sequence
Get array of Glyph index for the processed string
Display string using glyph index to get glyph from font file.

I have modified the TextToSvgPath example to display the Indic fonts.
I am attaching code in next message along with font files.

Looking for hints how to use HarfBuzz pre-processing generically for UPP display.
